I've seen those spike traps! I prototyped a variant of them a while back, and they were pretty neat. Might add them at some point. :)
What other traps could you think of?
They would be a good reason to have the kick other than only sawblades
Hmmm, what about a wrecking ball or mace spinning around, the wrecking ball would only knock you down, but the mace would pierce and could kill you. Also, maybe moving lasers, and the robots could jump when they pass!
